. PORTABLE CONTAINER COMPLETE WITH FILTER, FOR WATER OR OTHER LIQUIDS Filed Aug. 6, 1938 QORNELI'Q FIRES Patented Nov. 26, 1940 stares PATENT oer-loa PORTABLE CONTAINER COMPLETE WITH 1 Claim.

This invention consists essentially of a water container, readily portable and complete with its own filter, thus assuring at any moment, water of absolute purity; and relatespreferably to a canteen possessing the advantages above mentioned.

As is well known the existing type of canteen is the container in most general use, amongst all portable water vessels, for it constitutes an essential part of military equipment and it is in common use by workmen in railroad gangs and the like, in all cases where service requirements necessitate their presence at places distant from supplies of drinking water. However, the existing type of canteen, although it fulfills requirements satisfactorily as a water container does not assure the soldier on the march, or the Workman in the depths of the Woods a constant supply of pure water, always comparatively fresh. Finally, soldiers and workmen frequently run the risk of filling their canteens with polluted water, and of contracting fevers and intestinal illnesses as is common knowledge.

Consequently this invention represents a great hygienic advantage, from the point of view of the individual, soldier, workman or others, and a further great advantage from the collective point of view, for it reduces considerably the sickness percentage in army units in action or on the march, and in workmens gangs in railroad maintenance or platelaying services, or roadmaking.

The invention is illustrated in the annexed designs in the form of a canteen, in which designs:

Fig. 1 shows an outside view of the canteen in accordance With the invention, seen from the back;

Fig. 2 shows the same canteen in section, indicating the inside arrangement;

Fig. 3 is a. plan of the upper part of the canteen, showing its bulged form; and

Fig. 4 is a plan of the strap to support the canteen in correct position, to hang from a military belt or a belt of any other kind.

As will be clearly seen in Figs. 1 and 2 the container or canteen in accordance with this invention consists essentially of: a body of aluminium or other suitable light weight material I, slightly curved inward so as to be comfortably adaptable to the hip of its carrier, Figure 3, having at its upper part a perforated stopper 2, and at its lower part a comparatively wide spout or neck 3, provided with a stopper 4, which hermetically seals the spout 3 and at the same time serves as a drinking vessel; a filter cylinder 5 conveniently secured to the inner part of the spout 3 and projecting inwardly into the canteen body I, up to a certain height; a vertical stem 6 firmly secured at one end to the filter cylinder 5 with its other end, which is threaded, passing through the central hole 1 oi the top stopper 2 projecting slightly beyond and above the said stopper; a nut, 8, screwed on to the threaded projecting extremity of the stem 6 so as to secure the said stem and I the filter cylinder 5 in position; a strap 9,.with a narrow centre part I0, extending downward in a wide part II, havinga circular aperture, also wide, I2, ending in a narrow extremityv with a buckle 13, the said central. part of the strap Ill being extended towards its other end in a wide part M, with an oval aperture l5, ending in a narrow tip with holes I6, to fasten up in the usual way with the aforesaid buckle; and a strap-guide H on the inner side of the centre part ill, shown by dotted linefastened to the belt by rivets I8.

To apply the belt 9 to the canteen 8,the belt aperture i2 is threaded over the spout 3, until its annular rim l2a gets between the upper and the lower surfaces of the said spout of the canteen I. In this way, the narrow part Ill passes to the other side or" the canteen, opening [5 being threaded over the stopper 2 in such a way that its annular rim I50, fits into flange 2a and the corresponding upper surface of canteen I. Obviously the two opposite ends of the belt I6 and i3 meet, and can then be buckled together. Finally the canteen may beattached to the body belt or the like, by threading the same body belt through the strap-guide H as far as convenient.

By Virtue of the arrangement of the filter 5 in the lower part of the canteen, the water con-- tained in the canteen will be filtered up to the last drop. Onthe other hand the liquid eventually warmed by the heat of the human body or by the outside temperature will lose part of its heat in the filtering cylinder and will thus be comparatively fresh when it reaches the mouth of the user of the canteen.

It will be understood that this invention is applicable to all kinds of portable vessels such as, for example, bottles, fiasks and the. like.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is tobe performed, I declare that what I claim is:

A portable canteen comprising a reservoir having an outlet opening in the lower portion thereof for the discharge of water therefrom by gravity, a filler opening in the upper portion of said canteen, a closure for the filler opening having an aperture therein, a filter body projecting through the outlet opening into th interior of the reser-' lecting filtered water.
